Richard Agar says his players must be tougher for longer periods to start picking up wins.
Trinity showed glimpses of what they can become as a team and after two tries at the start of the second half looked set to push the in-form Tigers all the way.
But the Wildcats were unable to maintain the momentum they had built and Castleford wrestled back the ascendency and finished the game the stronger to add gloss to a deserved victory.
Agar thought the Wildcats contributed to their own downfall.
“The biggest issue for us at the moment is that it (positive signs) is in parts and it’s in spells,” he told the gathered press.
“Our ability to tough it out when we’re tired and under fatigue to keep doing what we’re doing is the issue for us at the moment.
“I thought we came up with some poor one-on-one misses early doors for soft tries and we then worked our way back into the game and challenged them in the first half. Again, we looked like we ran out of gas and ran out of gas badly.
“I can see some reasons for that. There’s a lack of pre-season for some blokes and there’s some blokes coming back from longer term injury but more importantly, it’s what we’re doing with the ball.
“A classic example was where we were attempting to clear our own line and made a mess of the kick play. I don’t think we ever really got back into the game after that. We need to help ourselves a bit more and show a little bit more toughness.”
Agar revealed that Danny Kirmond was forced from the field with a quad injury which makes his a strong doubt for Monday’s game against Huddersfield Giants, whilst Reece Lyne and Dean Collis are also expected to struggle to back-up again on Monday.
